- the invention further relates to a connecting element and a joining device.
- the punch riveting method For joining at least two workpiece layers, for example, the punch riveting method is generally known. This method serves to insoluble force and form-fitting joining of the workpiece layers with special punch rivets as connecting elements with which the workpiece layers are punched and joined without prior punching in a combined punching and forming process.
- the punch rivet serves as a disposable cutting punch and is thereby also transformed itself.
- the workpiece layers are first positioned over a die by means of a blank holder. Subsequently, the punch rivet is acted upon by a punch with a force and pressed into the joining parts. Depending on the riveting method, the rivet shank cuts through at least the uppermost workpiece layers and is then spread in the matrix.
- a generic joining method for joining at least two plate-shaped workpieces of identical and different materials, in which a self-piercing rivet connection is combined with an adhesive connection.
- an adhesive is introduced into the joining zone between the workpiece layers, which additionally glues the workpiece layers together.
- the adhesive flows radially outward from the joining zone but does not reach the cut surfaces and does not act against delamination.
- US 2010/0088880 A1 discloses a connecting element which has an adhesive within the rivet shank, which is pressed by passage of the rivet shank to the outer surface of the rivet shank only after the beginning of the joining process, namely during the punching process. Before the beginning of the joining process, the connecting element is not coated on the outside. task
- the invention is based on the object to improve a method for joining the aforementioned type, in particular to largely or completely avoid delamination of fiber-reinforced workpiece layers in the region of the cut surfaces. Furthermore, a connecting element and a joining device for carrying out the method according to the invention are to be made available.
- the connecting element is heated to the extent that a coating of the connecting element melts and wets the cut surface in the first workpiece layer, in particular completely closes and that after a cooling process, the re-solidified coating adheres to the Thomasflä- surface of the first workpiece layer, the cut surface by the coating in particular completely closed and thereby prevented at workpiece layers made of fiber-reinforced plastic delamination.
- One or more of the workpiece layers may be pre-punched so that a cut surface resulting from the pre-punching is covered by the coating.
- the cut surface can also be generated during the process according to the invention by the connecting element itself.
- punched connecting elements are suitable.
- a piercing connection element is to be understood as meaning a connection element which has one or more workpiece layers during the joining process can punch through, for example, a punch rivet.
- a punching connection element can also be carried out without difficulty by a previously introduced pre-hole in one or more of the workpiece layers, so that the connection element itself does not punch a hole in the workpiece layers, but essentially serves only to join the workpiece layers.
- at least one of the at least two workpiece layers, in particular the first workpiece layer, before the start of the method in the region of the joint is a continuous closed surface without a pre-hole.
- the processing cost is reduced.
- Punch rivets in particular semi-hollow punch rivets as punched connecting elements, are particularly suitable.
- the lowermost workpiece layer (thus the second workpiece layer in the case of two workpiece layers) is preferably not or not completely punched through the stamped rivet, so that a tight joint is formed.
- the generic term "punching connecting element” is also to be understood as meaning known connecting elements which do not completely punch through all the workpiece layers but which are not or only partially punched through a workpiece layer, in particular the second of two workpiece layers. especially when all workpiece layers are completely punched.
- the connecting element has a through hole or a threaded hole, more functions can be integrated into the joint or tied at the joint.
- first workpiece layer consists of a fiber-reinforced plastic
- second workpiece layer consists of a metallic material, in particular a steel alloy, aluminum alloy or magnesium alloy.
- the coating of the connecting element preferably has an adhesive or plastic, in particular a polymer material. For punch rivets it is sufficient if their rivet shank is coated.
- Particularly suitable joining devices which comprise a die, a hold-down and a die as tool elements, of which at least one tool element is heatable.
- the stamp is heatable.
- the joining device comprises a temperature control device by means of which the temperature of the tool element, in particular of the punch, can be adjusted and maintained at a constant level.
- FIGURES AND EMBODIMENTS OF THE INVENTION In the following, the invention will be explained in more detail with reference to an advantageous embodiment shown in the drawings. However, the invention is not limited to these embodiments. Show it:
- FIG. 1 shows a first workpiece layer 1 and a second material layer 2 to be joined thereto, which are introduced and positioned in a joining device.
- the joining device known per se comprises a die 21, a hold-down 24 and a punch 26.
- the first workpiece layer 1 consists of a fiber-reinforced material, in the matrix 1 a, a plurality of fibers 1 b for reinforcing the matrix material 1 a are introduced.
- this fiber-reinforced material is a glass or carbon fiber reinforced plastic with aligned long fibers.
- the second material layer 2 consists of a metallic material, in particular of a steel alloy, aluminum alloy or magnesium alloy.
- the second material layer 2 rests on the die 21. On the second material layer 2 lies flat on the first material layer 1.
- the two material layers 1, 2 are fixed by means of the blank holder 24 relative to each other in the joining device.
- a connecting element in the form of a punch rivet 10 is positioned in the joining device above the joint.
- the punch rivet 10 is designed as Halbhohlstanzniet, but could also be a full rivet in a modified version.
- the punch rivet 1 comprises a rivet head 11 and a rivet shank 12.
- the rivet shank 12 is provided with a coating 15, which preferably consists of a polymer which is applied to the rivet shank 12 as an adhesive or plastic.
- the joint is shown immediately after the combined punching and forming process in which the punched rivet 10 powered by the punch 26 is punched through the first workpiece layer 1 and introduced into the second workpiece layer 2.
- the punch rivet 10 serves as a disposable cutting punch and is itself also transformed by being spread apart by the force applied by the die 21 counterforce on a molding in the die 21. In the present case, this happens in particular without completely piercing the second workpiece layer 2.
- a peripheral, cylindrical cut surface is created due to the punching.
- the matrix material of the matrix 1 a and the fibers 1 b are cut through in the region of the cut surface. In the edge zone of the cut surface, the fiber ends of the fibers 1 b are open and are not covered by matrix material of the matrix 1 a and protected. This results in delamination of fibers 1b and matrix material 1a in the cut surface.
- the first workpiece layer 1 is pre-punched before the beginning of the method according to the invention, so that the cut surface in the first workpiece position is not or only partially generated by the punch rivet 10.
- the joint is heated by the punch 26 by the punch 26 is heated and is heated, in particular electrically or inductively.
- the die 21 and / or the hold-down device 24 can also be heated.
- the coating 15 of the rivet shank 12 of the punch rivet 10 melts due to the introduced heat and wets the cut surface in the first workpiece läge 1, so that the coating completely closes the cut surface in particular.
- the figure 4 shows, the joint is cooled by the heat input is switched off in the punch 26 and in particular additionally actively cooled. For this purpose, the punch 26 is already removed from the joint.
- the coating 15 now solidifies on the cut surface of the first workpiece layer 1 and thus covers the fiber ends of the fibers 1 b, which are thereby protected from delamination.
- the joined workpiece layers 1 and 2 are removed from the joining device in a last method step (FIG. 5).
